Injection Molding Service manufactures 3D metal parts.
May 2, 2008 -
By utilizing Xyloy(TM) metal alloy, metal parts can be injection molded on standard machinery and in tools designed for plastic. Finished parts can be textured or have standard finishes. In addition, molded parts can be painted and powder coated. Company will manufacture parts for OEMs that are seeking to find more productive ways to produce metal parts, or replace under-performing plastic parts with metal. Full art-to-part design and molding services are offered.

Materials Firm Can Now Injection Mold 3-Dimensional Metal Parts for Industry
WARWICK, RI (April 15, 2008) - In major moves that promise to capture the attention of OEMs in both the plastics and metals industries, a fast-growing, innovative materials developer can now injection mold metal parts on standard injection molding machinery, and in tools designed for plastic. This breakthrough comes about as a result of a new metal alloy developed by Cool Polymers, Inc. - Xyloy (TM) - that is stronger than die cast metal parts and has no porosity. Xyloy is molded in 3-D, net shape parts in high volume that offer strength, stiffness, conductivity and processability, with tooling guaranteed for the life of the program.
Company officials note that the new process is NOT metal injection molding (MIM), but rather standard injection molding of Xyloy injection moldable metal. Many designs currently being die cast or plastic designs that might benefit from metal properties can now be injection molded using proprietary Xyloy injection moldable metal. Shrinkage is less than 0.5%. The company will manufacture parts for OEMs that are seeking to find better and more productive ways to produce metal parts, or replace under-performing plastic parts with metal. Cool Polymers offers full art-to-part design and molding services.
Of particular note is metal parts made out of Xyloy metals can be manufactured - injection molded - with existing tooling for plastics. Further, unlike metal parts, no secondary operations after molding are necessary, and the tooling is guaranteed for the life of the program. Finished parts can be textured, or can accept standard finishes. In addition, molded parts can be painted and powder coated.
Injection molding cycle times of nonporous Xyloy metal parts are on a par with plastic parts. Again, company officials point out that the material and process are NOT metal injection molding or any other plastic/metal production process. Rather, because of the special characteristics of the new Xyloy high strength injection moldable metal, parts are injection molded on standard injection molding machines. The results are metal parts that have superior properties over comparable parts made of either plastic or metal.
Properties of the new thermoplastic metal are:
o Ultimate Tensile Strength of 47 kpsi (325 Mpa)
o Yield Strength of 36 kpsi (250 Mpa)
o Elongation at Break of 2%
o Modulus of Elasticity 13000 kpsi (90 Gpa)
o Specific Heat Capacity 0.1 BTU/lb°F (0.4 J/g°C)
o Thermol conductivity 110w/mk
Cool Polymers, Inc. is the oldest and undisputed leader in thermally conductive plastics, with more than 100 million customer molded parts in use. The firm also provides off-the-shelf and custom parts made from these proprietary polymers, plus full design and prototyping assistance. Products, polymers and services also available from the company are thermally conductive plastics for dielectric heat plates, folded-fin heat sinks, thermal interface and gaskets, functional heat sinks, compression molded solid shapes, complete design and prototyping services, product assembly and packaging.
